=== Developer Tools ===

<ul>
<li><p>''' '''Toolbox</p>

<li><blockquote><p>Julian fixed a [https://bugzilla.mozilla.org/show_bug.cgi?id=1760992 ''bug''] when using the picker on UA Widgets (e.g. &lt;video&gt; elements)</p></blockquote></li>
<li><blockquote><p>Storage Inspector wasn’t reflecting Cookies being updated in private tabs, this was fixed in [https://bugzilla.mozilla.org/show_bug.cgi?id=1755220 ''Bug 1755220''] </p></blockquote></li>

<ul>
<li><blockquote><p>Support for the browsingContext.close command landed ([https://bugzilla.mozilla.org/show_bug.cgi?id=1694391 ''bug'']) which allows users to close a given top-level browsing context (aka tab).

<li><blockquote><p>Optional hosts and origins should now be set as command line arguments, and not from preferences anymore ([https://bugzilla.mozilla.org/show_bug.cgi?id=1759994 ''bug'']).

== This week I learned ==

<ul>
<li><p>[gijs] Someone I spoke to didn’t know this one neat trick: on treeherder, you can filter jobs by test paths! Click the funnel icon on the top right, then in the dropdown on the left select “test path” and put in a path to a directory or file, and click the “add” button. Treeherder will hide all the jobs not running tests there. Useful when looking at treeherder to see when particular breakage was introduced, or which jobs run which tests. The URL will also reflect this selection.</p>
